BMW 8 Series (2018-present) Pros and Cons

Pros	Cons

xDrive 4x4 models perform in all weathers	Not as luxurious as a Mercedes S-Class Coupe
Choice of convertible, coupe and four-door body styles	Coupe and convertible are cramped in the back

Quick Summary

The BMW 8 Series (2018-present) is a sophisticated grand tourer that straddles the middle ground between the overtly sporting Porsche 911 and the sumptuous Mercedes S-Class Coupe. This modern iteration revives a legendary model name and serves as BMW's flagship performance vehicle. Available in coupe, convertible, and four-door Gran Coupe configurations, it offers a striking design and opulent cabin. The M8 Competition variant represents the fastest and most powerful road car BMW has ever produced, delivering truly breathtaking acceleration and performance.

The 8 Series combines lusty performance across its range with a reasonably cushioned ride and accurate steering. Boot space ranges from 350 litres in the convertible to 440 litres in the Gran Coupe. Running costs vary significantly depending on the model chosen, with the diesel 840d achieving around 40mpg whilst the M8 Competition manages only 22mpg in mixed driving. All variants incur £475 annual road tax, though more powerful petrol models face a £1,850 first-year rate. Insurance sits in group 44 minimum, with the M8 Competition in the highest group. Servicing costs can be managed through BMW's fixed-price plans at £30-£45 monthly depending on specification.

Best for: Buyers seeking a refined grand tourer with genuine performance credentials, those wanting a middle ground between extreme sportiness and ultimate luxury, and drivers who value choice in body styles and powertrains.

Not ideal for: Those prioritising maximum thrills (like a 911), ultimate luxury (like an S-Class Coupe), or requiring spacious rear seating in two-door variants, or budget-conscious buyers given running costs and insurance premiums.


Comparison vs Key Rivals



The Verdict

You should buy the 8 Series if: You seek a refined grand tourer with genuine performance, want a middle ground between extreme sportiness and ultimate luxury, or value choice in body styles and powertrains.

Consider alternatives if: You prioritise maximum thrills, ultimate luxury, require spacious rear seating in two-door variants, or are budget-conscious given running costs and insurance premiums.

Competitive Position: The BMW 8 Series occupies a compelling middle ground in the premium performance coupe market. Whilst the Porsche 911 offers greater thrills and the Mercedes S-Class Coupe delivers superior luxury, the 8 Series balances both attributes effectively. It outperforms the Aston Martin Vantage in user satisfaction and offers more practical body style options. The 8 Series represents an attractive proposition for discerning buyers seeking a sophisticated grand tourer with genuine performance credentials, though it inevitably means no version truly excels in any single area compared to its more specialised rivals.
